1.5.4.3. RF Cabling
The RF cabling and connectors inside the TGB are selected due to
their low-loss characteristics. No cables or connectors should be
changed/replaced.
1.5.5. Electronics Assembly
The Electronics Assembly is the heart of the TGB radio. It contains all
of the RF and signal processing electronics housed in a single card
cage and provides for an interconnecting Backplane.
1.5.5.1. RF Assembly
The RF Assembly converts (using amplifiers, mixers and filters) the RF
signal from the antenna to an IF signal used by the A/D Assembly,
provides a high performance 1.25W Transmitter stage, and provides a
programmable clock signal for the A/D card . It also provides AGC
functions.
1.5.5.2. A/D Assembly
The A/D Assembly digitizes the IF signal from the Receiver Assembly.
The digitized information is then delivered to the CPC Assemblies.
1.5.5.3. CPC Assembly
The TGB contains 2 dual channel CPC assemblies, supporting a
number of different modulation schemes. The CPC assembly
performs filtering and demodulation of inbound messages and delivers
them to the fusion processor.
1.5.5.4. Fusion Processor Assembly
The Fusion Processor Assembly collects serial messages from all 4
CPC channels, combines them, and delivers them to the TGB
Controller.
1.5.5.5. DC/DC Supply
The plug-in DC/DC Supply converts 24VDC Power to standard
operating voltages (+3.3VDC, +5VDC, +/-12VDC).
1.5.6. Breakout Panel Assembly
The purpose of the Breakout Panel is to function as an interface between
the Fusion Processor and the “external world”. It provides a termination
point, and more importantly Transient Voltage Suppression, of signals
coming into the Fusion Processor. TVS devices protect all Alarm Inputs,
Modem Lines, and Ethernet Lines.
